Q I have an office job that keeps me at my desk in cube-land for hours at a stretch. Sometimes it's hard to stay focused and find that I run out of energy. What could I do to avoid energy slumps?
A Some simple movement and nutrition steps will help, and also look at your life outside of work.
The inner game
Start with an assessment of your day. Notice the time and what you've been doing when you have the most energy. It may be certain times of day, after you've had a particular thing to eat or drink, or after a certain task. Also notice when you slump, focusing on the same items. Take an even broader look to determine the effect of activities outside of work, for example, exercise, stress and sleep. Try keeping an "energy diary" so that you can more easily identify patterns.
Evaluate what you're not doing. Look at your diet and whether you're moving around during the day to identify gaps you could address. Include whether you take breaks when you can and how you use them.
Consider the opportunities you have (15-minute breaks every morning and afternoon) plus the constraints (limited space and privacy) so that you plan energizer options that are feasible. Also look at inner constraints you may be imposing, such as fear of reactions from co-workers or simple inertia -- change does take some effort and determination.
The outer game
There are many ways to get energized at work, even if you have a fairly constrained job.
